how to make core design of transformer on custom transformer winding

Primary Winding Calculations
Basically three important parameters needs to be figured out while calculating the primary winding of a transformer, they are as follows:

Primary Winding Current = (Secondary Volts × Secondary Current) ÷ (Primary Volts × Efficiency), the average value for the efficiency of any transformer nay be presumed to be 0.9 as a standard figure.
Number of Turns = TPV × Primary Volts
Primary Winding Area = Number of Turns / Turns per Sq. cm (from the table A)

Reading Table A is easy – just find out the relevant figures (wire SWG and Turns per sq.cm.) by tallying them with the closest matching value of your selected primary current.

Secondary Winding Calculations
As explained above, with the help of Table A you should be able to find the SWG of the wire to be used for the secondary winding and the TPV simply by matching them with the selected secondary current.

The Number of turns for the secondary winding is also calculated as explained for the primary winding, however considering high loading conditions of this winding, 4 % extra turns is preferably added to the over all number of turns. Therefore the formula becomes:

Secondary Number of Turns = 1.04 × (TPV × secondary voltage),

Also secondary winding area = Secondary Turns / Turns per sq. cm. (from table A).
